Does anyone do affiliate marketing?

This is something that I really want to get into, but I am unsure of how to start. I don't even have a blog yet, so I am thinking of subscribing to the Niche Blogger, but that isn't cheap. Or the Chris Farrell Membership thing, but I'm not even sure if that is affiliate marketing.
Any thoughts about this?

I have recently started getting more serious with affiliate marketing. My first serious campaign is making a little money every week now all I have do is just repeat what I did with that. I used Squidoo and HubPages for my affiliate properties. What got me on the right track was a product called "One Week Marketing". It is a very good product if your just starting to get into affiliate marketing. Check my profile to see more about it. There's also a free Squidoo book there too.

Basically Squidoo is where you can put up like a web page, which is called a lens. You add what is called a modules to your lenses, like a text module, comment modules, you can have polls and add eBay and Amazon modules to make money. Squidoo has a revenue share program so you can make money just by making lenses depending on how much traffic you get. The free e-book on Squidoo in my profile can tell you more.

I do, and I have to say that it is the best way to earn the big bucks. So I recommend it if you are serious about your online earnings. There are tons of different networks you can join, try looking around and taking a look at a lot of them to see what suits you the best.
